ers, of which the folloi ingis a specification.

My invention relates to improven'ients in snap fasteners and particularly to the socket member thereot'.

.It has for its object; to proi-idea socket member of a snap 'fastener constructed of two plates on diskswhich will be strong and durable andn'hich shall -'also,possess the requisite resilience and the quality of firmly and securely holding the ball member of the fastener.

Otherobjects and advantages of my invention will be referued to in the detailed dc'eription of the invention which follows or will be apparent therefrom.

One'embodiment-of a convenient form of my inventioiris illustrated in the accompanying drawii'ig, but it will be understood that changes in the details otconstruction. and in the form and contour of, the parts entering into the construction thereof may be made withinthe scope of the claims without departing from my said invention.

In the drawings z -l igure 1 is a plan View of one side of'the socket member of a. lastenor W- ;h the ball or stud of the ball member projecting through the socket thereof;- Fig. is a plan view of thebottom of the a lastenerwhich is in engagement with a socket member, the edges of the latter appear-i beyond the edges of the ball member ;--l 'ig. 3 is a transverse section on the line 3 3 of Fig. 1 ;l*ig. 1 is a. plan View of one side of the socket member of the fastener, similar to Fig. 1,'t he'ball tion of said members.

member being omitted; and Fig. 5 is a plan view of the oppositeside. of the socket member, the said ball member being omitted. 1 Referring to the drawings, 1 designates what may be termed the flange or body portion of the ball member of a snap fastener, 2 the ball or stud of thesaid hall member and 3 the connecting neck portion thereof.

The said ball member is shown. in engage ment with the socket member of the fastener in order to illustrate the m anner of coopera- The ball member is adapted to be secured by nieansof threads tend beyond t.

(not shown) passed through the thread holes or openings 4, and-whichfthreads are; also passed through the garment or grartiole to which it is desired to secure the ,said ball member. Any, other, means .may be employed for securing the ball member to'said garment or ,other article. The socket member of the fastener as illustrated 'consists'of ti-vo plates, 10 and 11, indisk form, inter locked so that together they constitute a structure in which, said plates co'operate to form the socket member .of a fastener having'the requisite resilience and spring action which enables it to firmly hold the ball or stud of the ball member oft he fastener.

-The plates 10 and 11 are arranged 'in substantial parallel relation with respect to and incontact with each other.' The plate 10 is of greaterdiameter and area than the plate '11, so that the :outer edges thereof, when the plates are placed againsteach other, ex-

he outer edgesof the plate 11. The, overhanging edges of the plate 10 are turned over and around th'e'edges of theplate 11, as indicated at 12, in Fig. 3 of the drawing. The extreme outer edge 13.0f the said plate 10 extends over the plate 11 a short distance upon the side thereof opposite to the main or body portion of the said plate 10. By this construction and arrange ment. the outer edge of the plate 11 is enfolded within the bent over outer edge portion of the plate 10, as is indicated at 12, and the two plates are thereby secured togather. The plate 10 is provided with a hole or opening 14, and preferably, though not necessarily, the portion of the said plate surrounding-the said hole' or opening is depressed as indicated at 15.

Radial slits or slots 16 extend from the center outwardly av suitable distance in the plate 11. The presence of these slits or slots in the plate 11, causes the formation of pointed projections or prongs 17 at the central portion of the said plate 11. Theseprongs or projections are bent slightly latterly, as indicated at 19. and are then bent and extended through the opening ltin the bent down into. or substantially into. contact with t rsurtizu'e ol' the Silltl depressed portion. reason of the depression of the portion oi the member 10 around the opening 14, the points ofthe prongs orvpro- 1 ect1ons 17 are t"a greater or less extent protected. y While in Fig. 5, of the drawings, the slits or slots 16 are shown as of considerable width, it should be understood, in the first place, that the drawings are madeupon an enlarged scale and, in the second place,

that the width of the said slits or slots, may

be varied, within limits, at the willof the-- manufacturer or person constructing the fastener.

' T Although in the drawingsthe ball or stud of the ball member is illustrated as having been inserted through 'the socket of the socket member from the side constituted of the plate 11, it is to be understood that, if desired, the ball or stud-of the ball member may be insertedfrom the opposite side of the socket m'ember, the said member operating as efficiently when the ball or stud is inserted from one side as when inserted 1. The socket member of a snap fastener comprising-two centrally apertured plates one being of greater outside diameter than theotherand having its outer edge portion folded over to 'inclose the corresponding edge of the other and said other'plate carrying projections from its inner ed e,. said projections being bent outwardly t en reversely and arranged to extend through the aperture in and engage the opposite side of the first plate,' said projections being en adjacent edge of said tirely free of the first plate. l

2. The socket member of a snap fastener comprising 'two' centrally apertured plates in parallel relation with each other, one being of greater outside diameter than the other and having its outer edge' portion folded over to inclose the corresponding edge of the'other, and said other plate carrying integral projections from its inneredge, said projections being bent outwardly then reversely and arranged to extend through the aperture in and to inclose the inner edge portion of the first plate, said projections being entirely free of the inner edge of said first plate.

. In testimony that I dlaim the foregoing as my invention, I have hereunto signed my name this 15th day of August, A. D. 1911. JAMES P. \VILLIAMS. In the presence of GEO. H. WEIDNER, CARRIE E. KLEINFELDER.
